I think 'WC singing' comments and 'promises' were there to just down play our real targets, so when for example we put in a bid for Vucinic , we don't end up negotiating Higuain's price for him with Roma.
First, they publicly declared how they rate the players. Comments of Aguero, Higuain, Vucinic and so on.
And second, there's this supposed '30+mil saving' of our budget for signing of a WC player

so with our tight budget when we say 15mil for Vucinic, Roma better think twice before rejecting it when they clearly wanted to sell the player.
and that was pretty much the case if you guys remember Roma asked for
20+mil at first, then it all cooled down and suddenly Sabatini came out with those comments which apparently he accepted the intial offer.
